Yes a igneous rock can be changed into another igneous rock. the reason behind it is when rocks melt they become magma or lava. when lava flows on the surface of the earth it crystallizes quickly and makes small crystals. but when they cool slower they make larger crystals. yes igneous rocks can change but only through extreme temperatures.
Radio waves are used in cell phone wireless communication by this: Radio waves are released from the cell phone and travel to satellites in the stratosphere. After they reach the satellite, they are redirected to the recipient of the call/text.
Hope this helps! Can I have brainliest please?
Answer:
d = 185.26 meters
Explanation:
It is given that,
Launching angle of the projectile,
Initial speed of the projectile, u = 48 m/s
Let at distance d the projectile hits the ground from the launch point. It is equal to range of the projectile. Its formula is given by :
Substituting all the values in above formula. So, we get :
d = 185.26 meters
So, the distance between the launch point and the point where it hits is 185.26 meters. Hence, this is the required solution.
The SI system was created so most countries can have the same units and cause no confusion.
